Description
DURAN® dropping funnel blank, cylindrical with stopper seat for ISO 4800, is a borosilicate glass 3.3 intermediate with a nominal volume of 1 l intended for further processing into finished dropping funnels. These blanks enable metered liquid addition to reaction mixtures and support phase-separation workflows once completed with suitable stopcocks and joints. The cylindrical body incorporates a stopper seat conforming to ISO 4800, providing a standardised glassware starting point for laboratory fabrication. Produced from borosilicate glass 3.3 by Duran/DWK Life Sciences, the article combines chemical resistance with thermal durability suited to typical laboratory conditions. Each unit has a net weight of 0,495 kg and is supplied in packs of 10 pieces. The blank is designed specifically as a raw body for conversion into dropping funnels used in chemical synthesis, sample preparation and analytical procedures requiring controlled liquid dosing. Its geometry facilitates subsequent glassblowing or assembly steps while maintaining dimensional consistency for ISO-compatible fittings.
This article is part of Dropping funnels, in Funnels.

Questions about DURAN® ébauche pour ampoule à introduction, cylindrique, avec lit de bouchon pour ISO 4800
What is this article?
DURAN® ébauche pour ampoule à introduction, cylindrique, avec lit de bouchon pour ISO 4800 is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Entonnoirs à addition, inside Entonnoirs, in Matériel de laboratoire.
A dropping funnel adds a liquid slowly into a closed reaction through a stopcock and usually a ground joint. A pressure-equalising arm keeps the funnel from air-locking. The joint size and the volume are the specification.
A funnel guides a liquid or a powder into a narrower mouth. A filter funnel holds a paper. A Büchner funnel is the flat perforated plate used with vacuum. A separating funnel has a stopcock so two liquid layers can be run off one at a time. A dropping funnel adds a reagent slowly into a reaction. The bore and the stopcock are the parts that matter. This glassware is listed under ISO laboratory glassware.
